  • An MBS PDSCH scheduling method and a method for determining whether data is transmitted initially or retransmitted in Point To Point (PTP) data transmission will be described briefly at first.
  • PTM Point To Multi-point
  • a base station transmits scheduling signaling DCI on a Physical Downlink Control Channel (PDCCH) to schedule a data channel PDSCH, and the DCI is scrambled with a Cyclic Redundancy Check (CRC) using a G-RNTI.

  • UEs User Equipments
  • Unicast scheduling is also called as PTP scheduling, a UE-specific PDCCH is used for a scheduling instruction, and a data channel is a UE-specific PDSCH.
  • the base station transmits scheduling signaling DCI on the PDCCH to schedule the data channel PDSCH, and the DCI is scrambled with CRC using a C-RNTI.
  • a scrambling code sequence for scrambling the scheduled data channel PDSCH is generated in accordance with the G-RNTI or the C-RNTI.
  • each UE merely receives the scheduling signaling transmitted by the base station to the UE itself, and receives the PDSCH in accordance with the scheduling signaling.
  • NDI Hybrid Automatic Repeat reQuest
  • the NDI is directly determined to be toggled.
  • the data is determined to be transmitted initially, and when the NDI is not toggled, the data is determined to be retransmitted.
  • received PDSCH data is not combined with any cached data, and instead, it is demodulated and decoded individually.
  • the received PDSCH data is combined with the cached data for a same HARQ process, and then demodulated and decoded.
  • the above-mentioned method for determining whether the NDI is toggled is merely adapted to the UE-specific RNTI, i.e., DCI scrambled with the C-RNTI, rather than being adapted to the group scheduling where the DCI is scrambled with the G-RNTI or UE individual scheduling where DCI is scrambled with the C-RNTI.
  • the group scheduling where the DCI is scrambled with the G-RNTI or the UE individual scheduling where DCI is scrambled with the C-RNTI when the above-mentioned method is still used to determine whether the NDI is toggled, an erroneous determination result may occur.
  • the base station schedules a Multimedia Broadcast Service (MBS) PDSCH using the G-RNTI.
  • MBS Multimedia Broadcast Service
  • This HARQ process number is not used before, so each of UE1 and UE2 uses its own values of the NDI, and the values of the NDI may be different before DCI-0.
  • the G-RNTI scheduling is performed with respect to one group of UEs, so no matter whether the value of the NDI is set as 1 or 0, it may be the same as the value of the NDI for one of the UEs.
  • 1 is used to transmit an initially-transmitted MBS PDSCH.
  • the NDI is toggled, so the MBS PDSCH is determined to be transmitted initially, as expected by the base station.
  • the NDI is not toggled, so the MBS PDSCH is determined to be retransmitted, and at this time, the determination result is wrong.
  • DCI-6 the base station schedules a unicast PDSCH scrambled with the C-RNTI; in DCI-7, the base station schedules the initially-transmitted MBS PDSCH scrambled with the G-RNTI; and in DCI-8, the base station schedules an initially-transmitted unicast PDSCH scrambled with the C-RNTI. Due to the missed detection of the UE in DCI-7, the transmission in DCI-8 is erroneously determined as the retransmission in DCI-6.
  • HARQ process numbers 1, 2 and 3 are merely used for the scheduling of an MBS
  • the other process numbers e.g., HARQ process numbers 4, 5, 6, 7 and 8
  • the HARQ process numbers are allocated inflexibly.
  • An object of the present disclosure is to provide an information transmission processing method, an information transmission processing device, and a UE, so as to solve the above-mentioned problems.
  • the method and the device are provided on the basis of a same inventive concept, and a principle of the method for solving the problem is similar to that of the device, so the implementation of the device may refer to that of the method.
  • the present disclosure provides in some embodiments an information transmission processing method for a UE, which includes the following steps.
  • Step 201 obtaining first DCI and first information, the first DCI including a first NDI.
  • the first information includes at least one of: a first scrambling RNTI type of the first DCI; a second scrambling RNTI type of second DCI, the second DCI being DCI received before the first DCI; a value of the first NDI in the first DCI; or a value of a second NDI in the second DCI.
  • the scrambling RNTI type is a C-RNTI or a G-RNTI.
  • the value of the NDI is 0 or 1.
  • Step 202 determining that the first NDI has been toggled in the case that the first information meets a first condition.
  • Step 203 determining that the first NDI has not been toggled in the case that the first information meets a second condition.
  • Step 202 the UE determines that data transmitted through a PDSCH is transmitted initially when the first NDI has been toggled, and subsequent to Step 203, the UE determines that the data transmitted through the PDSCH is retransmitted when the first NDI has not been toggled.
  • the first condition when the first condition is not met, it means that the second condition is met. That is, in the case that the first information meets the first condition, the first NDI is determined to be toggled, and in the case that the first information does not meet the first condition, the first NDI is determined to be not toggled. In other words, in the case that the first information meets the first condition, the first NDI is determined to be toggled; otherwise, the first NDI is determined to be not toggled.
  • the retransmission and initial transmission (also called as new transmission) of the data are generally considered as being performed in a same HARQ process, and the above-mentioned determination process is considered, by default, a process of determining whether the NDI is toggled in a same HARQ process number.
